Dragon Ball Super S02E09 - The Earth and Gohan in Dire Peril! Come Quick, Son Goku!

Piccolo takes Frieza's attack to save Gohan and dies in the process. On Beerus' planet, Beerus has developed an obsession for pizza and becomes furious when he learns that Goku and Vegeta ate the reserve pizzas Whis stored in his pocket dimension. Whis telepathically responds to Bulma's invitation for a strawberry sundae and relays her message of Frieza's revival and Piccolo's death to Goku and Vegeta. As Whis says it would take some time to reach Earth, Goku resorts to instant transmission on Beerus' advice, but realizes that instant transmission is impossible due to the large distance between Earth and Beerus' planet and the need to find a potent enough energy signature to pinpoint. On Earth, Gohan powers up to his maximum limit to give his father an energy source for instant transmission. Goku and Vegeta arrive on Earth in the nick of time to save Gohan, upon which Vegeta promptly executes Ginyu. As Goku and Frieza meet after a long time, Frieza transforms directly into his final form to demonstrate his new power. This results in the death of all his men except for Sorbet, who is at a considerable distance. Perplexed by Frieza's new power, Goku prepares to engage in a battle.
